A bizarre sighting in Astana, Kazakhstan, is taking the internet by storm after dozens-if not hundreds-of stunned witnesses reported seeing glowing lights forming a distinct L-shape in the night sky.

The now-viral footage shows a cluster of bright orbs hovering silently before aligning into an unusual geometric formation, The Caspian Post reports via foreign website.

Social media users have been quick to label the phenomenon as a “UFO,” with clips rapidly spreading across platforms and racking up millions of views.
